Title: Improvements in textile sliver coiling apparatus
Inventor: BROOKS JAMES
IPC: B65H67/04
Filed: 1963-09-04
Abstract: 1,005,578. Spinning process. T. M. M. (RESEARCH) Ltd. Aug. 25, 1964 [Sept. 4,1963], No. 34995/63. Heading D1F. In a sliver coiler, a line of cans 15 is supportable on a wheeled carriage or trolley 16 running along a track 17 whereby an empty or full can is supplied or removed. The floor of the trolley is apertured, as at 161, beneath each can so that, when an empty can is located at the coiling station, a can-driving disc 18 mounted on a spindle 19 (which may form part of mechanism such as described in Specification 947,799) is raised through the aperture to lift the can from the trolley and impart a rotary drive thereto: when a can is full, the disc 18 is lowered so that the can is again supported by the trolley and detached from the drive. The advance and withdrawal of the driving disc &c. are effected by a pneumatic lack 20 acting through a bell-crank lever 21, 22. As coiling into successive cans continues, the trolley is automatically indexed and secured (to locate the cans at the coiling station) by two separate pneumatic jacks, Fig. 4 (not shown). Successive cancarrying trolleys may be automatically coupled and uncoupled as they approach or leave the station. All the jacks are operated through valves, under the control of sliver length-measuring apparatus, in co-ordination with the stopping and starting mechanism of an associated draw-frame and may have overriding manual controls.

Title: Improvements in or relating to sewing machines
IPC: D05B3/20
Filed: 1961-09-29
Abstract: 940, 79. Sewing-machines. G. M. PFAFF A. G. Sept. 29, 1961 [Oct. 18, 1960], No. 35004/61. Heading D1G. A sewing machine for sewing a label or similar article to a fabric includes means for folding the edges of the label before stitching, the means comprising a retractable folding template and a work folding clamp movable past the edges of the template and having relatively displaceable, inwardly directed claws. The template 49 is shown in Fig. 1 in the retracted position occupied while the machine is sewing an already folded label 63 to a fabric 65. When the work feeding foot 62 is raised and the machine stopped the template, which is resiliently attached to one end of a lever associated with the stopping and starting mechanism, moves forward to resiliently engage the underside of the foot 64. The template is then manually depressed to permit an unfolded label to be inserted between label and foot, and a handle 25 is manually depressed to cause the jaws 28 of the folding clamp 29 to descend and fold the label ends around and beneath the edges of the template. The foot is then lowered, which allows the folding clamp to move up and away from the work, the template retracting as the machine is started up. The clamp 29 comprises two arms 27 spring pressed together and each pivoted to a block 24 and provided with a notch 32 on the inner edge 27a and a projection 30. The block 24 is slidable on a rod 18 slidably supported at its upper end in a bolt 20 attached to the frame of the sewing machine, its lower end being secured in a member 15 attached to a two part plate 11 connected with the presser foot lifting lever, not shown, to rise and fall with the foot 64. Extending from the member 15 are two projections 17 which respectively engage the inner edge 27a of the adjacent arm 27. A bifurcated locking member 22 slidably mounted on the rod 18 has surfaces 22a which taper upwards towards each other and co-operate with projections 30. When the foot has been raised and the handle 25 on the block 24 is depressed to operate the clamp 29 the arms 27 will move downwardly, surfaces 27a co-operating with projections 17 to spread the arms until the projections arrive at the recesses 32, the arms then being guided by the engagement of the surfaces 22a with the projections 30. As claws 28 pass the edges of the template 29 projections 30 pass beneath the member 22 and lock the clamp in the down position and the arms are moved in by the spring 31 to fold the edges of the label under the template (see Fig. 4). Lowering of the foot 64, prior to stitching the label, lowers the plate 11, the projections 17 engaging the edges of recesses 32 to spread the arms apart and release the projections 30 from beneath the member 22, a coil spring 23 then raising the clamp back to its original position. Specification 940,078 is referred to.

Abstract: 749,562. Tensioning bands &c. GERRARD INDUSTRIES, Ltd. Dec. 6, 1954 [Dec. 16, 1953], No. 35081/53. Class 45. [Also in Group XVII] - In a machine in which a metal strand is tensioned around a package and the ends of the strand are joined by power-operated means, means are provided to apply an initial tension to the strand, means operated by the attainment of the initial tension start a final tensioning mechanism, and means triggered after a predetermined movement of the final tensioning mechanism initiate operation of the strand joining means. A drum (not shown) is concentric with a cam-plate 3 and is rotated clockwise to feed band 2 to the package. The drum is rotated anti-clockwise to initially tension the band and withdraw surplus from the loop about the package. The tautening of the band during initial tensioning rocks a spring returned carrier 6 so that a pawl 8 carried by the cam-plate engages the drum to lock the cam-plate to the drum, and a gripper 10 on the cam-plate engages the band on the drum to prevent slip during the final tensioning. Further anti-clockwise rotation of the drum applies the final tension to the band, the degree of tension being determined by the setting of a sector-plate 12 at the periphery of the cam-plate. When the final tension is attained the sector-plate strikes a lever 13 on one end of a shaft 14 and causes a gib 17 at the other end of the shaft to strike a collar 18 on a spring-loaded bar 19. The resultant movement of the bar raises a latch 22 to permit rotation of a lever 24 by a spring 27 so that a semi-circular key 26 will lock a driven flywheel 28 to a camshaft 25. The cam-shaft makes one revolution, the latch falling back into the position shown to unlock the cam-shaft from the flywheel. During the revolution the cam-shaft operates the mechanisms which seal the band, retract the grippers holding the band, and set the machine main gear box to neutral gear. At the next band-feeding operation a lever 21 fixed to the shaft 14 is struck by a projection on the camplate to return the gib.

Abstract: 1,049,984. Computer programming arrangements; delay-line stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 24, 1965 [Sept. 29, 1964], No. 36419/65. Headings G4A and G4C. A computer comprises a storage device for storing instructions and data, and a push-down store the contents of a first register of which can be used for securing instructions from storage and can be incremented. Referring to Fig. 5 (not shown), a main store 200 can supply operand and instruction words via a buffer register to an arithmetic unit and field register respectively. Each instruction word has five fields each of which may be an operand address or an operation code as desired except that the first field of a first instruction word must be an operation code. The top three stages of a push-down store 270 are referred to (from the top down) as " instruction counter," " operand counter 1 " and " operand counter 2," and can be used for addressing instructions and operands respectively in the main store, the contents being incremented by one after each use. The first field of the field register is shifted into an operation register and decoded to (a) select (by means of a tag portion) one of the operand counters or the next field(s) of the instruction word as the source of the next operand address(es), (b) set a number from one to four into a field register shift counter to specify the number of field shifts required to place the next operation code in the operation register, (c) control the arithmetic unit, and (d) indicate when a subroutine is to be entered or returned from. For entry to a subroutine, the push-down memory is pushed down one position and the thus-vacated instruction counter is filled with the next field from the instruction word. For exit from a subroutine, the pushdown memory is pushed-up one position so that the contents of operand counter 1 enter the instruction counter &c., and the instruction counter is then used to read out the next instruction word. Thus the return address may be different from the exit address plus one. The number of shifts given to the contents of the field register is counted by a field counter and when it reaches five, the instruction counter is used to obtain another instruction word. Other embodiments.-Simpler similar embodiments having one operation code and one operand address per instruction word, and only one operand counter, and in which the branch address for subroutine entry is passed direct to the main store address register as well as to the push-down memory are described. Delay-line push-down store.-A recirculating delay-line store has provision for advancing or retarding its contents by one time slot on recirculation, and for incrementing the contents of selected slots by one.
